hello sir my wife has 3.5 months twin pregnancy [both in different sacks] during routine scanning radiologist found that one fetus has 2.8 mm nuchal transluncy[n.t] and other fetus has 2.1 mm nt . so they suggested for cvs for one fetus with higher nt. but the report was normal .but the torch test report was toxoplasma igg was 27.77 and toxoplasma igm was negitive , rubella igg was 22.86 and rubella igm was negetive , cytomegalovirus igg was 10.85 and cytomegalovirus igm was negetives. so please advice us that torch test normal or not and cvs is required for another fetus also .thank you
